lets see if i can describe my "solution"
it is a combo of some of the ideas avove.
I have my cage built to fit a plastic tray that was originally used in a pizza shop for its dough, about 3' wide and 2' deep (i'm sure that there are similar sized sweater boxes)
similar to above i have a hole drilled into the bottom but i placed it under my ficus pot so thathe more adventurous feeders cannot get out but the water can
beneath the tray i have a pair of plastic drawers that i picked up from Lowes. the hole mentioned above is over one and i use the other to hide all the "stuff" that we need. these drawers have a plastic structure around them that would make them stackable. it is this structure that supports the cage so that i can remove the drawer to empty it.
i run at least a gallon thru this every few days between the mister, the dripper, me misting and the humidifier.sometimes on the weekend i will have "rainday" and let the mister run for an hour or more. the drawer should hold about 2.5 or 3 gallons so if i get lazy and only empty it weekly i have no mess.
what i like is the fact that it makes it easy to remove the water and only raises the cage by about 7" or so
